Anyone having issues with the Mobile Hotspot? I seem to have lost the connectivity when I try to turn on the mobile hotspot. Initially I got message box about the Wi-Fi getting turned off. The configuration link is not active to try to change it. When I try to turn it on, it will come on, then turn off. This is after I upgraded my phone to ICS. Please let me know if anyone found a solution to this.

I have the same issue and was looking around the forums this evening for an answer outside of the standard 'reboot' or 'reset to factory defaults' as neither of those are acceptable answers for me. See this thread,https://community.verizonwireless.com/message/877311#877311, for someone else having the same issue.

From the home screen, touch Apps > Mobile Hotspot > Mobile Hotspot to turn on the hotspot.

Touch Configure Mobile Hotspot to change hotspot security and configuration settings:• Network SSID—Enter a unique name for your hotspot and touch Next

• Security—Select the type of security you want, and touch Save: WEP, WPA, or WPA2. Enter a unique password. Other users can access your Wi-Fi hotspot only if they enter the correct password.Note: Keep it secure. To protect your phone and hotspot from unauthorized access, it is strongly recommended that you set up hotspot Security (WPA2 is the most secure), including password.

• Broadcast Channel—Select a channel that minimizes potential interference. You may need to try different channels after your hotspot is active for a time.

Touch Save when the settings are complete. When your Wi-Fi hotspot is active, other Wi-Fi enabled devices can connect by entering your hotspot’s SSID, selecting a Security type, and entering the correct Wireless password.

When your Wi-Fi hotspot is active, other Wi-Fi enabled devices can connect by entering your hotspot’s SSID, selecting a Security type, and entering the correct Wireless password.Troubleshooting tips:Cannot access certain web sites using computer browserIf you're unable to connect to certain sites, try performing a force reboot.

Wireless Lan Supported Specs (Mobile hotspots)

Open (unsecured)

WPA2 PSK (secured)

Unable to establish connection with the phone

The wireless network may not be in range or has too of a weak signal to provide a successful connection. Check the signal bar to ensure you have strong connection.

Re-enter the key on the device to match the key configured on your phone. Make sure that the encryption type and security settings match on the device and your phone.

If WPA2 PSK encryption is in use, check that the key configured on the device matches the key entered on the phone.

"Forget" the connection. This will clear the connection and allow you to reinitialize with the your phone.

Turn off the connection from your device, turn the phone connection off. Turn back on your device first, then wait for 1 minute and then turn on and enable your hotspot to your phone.

Thanks B33, although that's not it. The issue is it HAS BEEN SETUP ALREADY, it just doesn't consistently work after. It's not my external device (laptop, etc) at issue, it's the Mobile Hotpsot process / service on the phone that's having the problem. The consistency here is the following:

When the Hotspot service / process is starting up (pressing on Mobile Hotspot and with the understanding this has already worked before and the setup like SSID, encryption choice, etc), a popup display will say "Checking Provisioning with the Verizon server", followed by "Turning Mobile Hotspot on" then a couple seconds later "Turning Mobile Hotspot off" right underneath the Mobile Hotspot line in the display. Additionally in the display at the very top of the screen you'll get a status update of "Tethering or hotspot active" for about a second and then it goes away, whereas if it was working it would stay.

This IS NOT an issue of improper setup as I can reboot the phone, or waste even more of my time by resetting to Factory Defaults and it will then start working for a while then will get back into this mode. This is a software issue with the phone. On the suggestion above, where it mentions 6.12.173.XT912.Verizon.en.US, I have version 6.16.211.XT912.Verizon.en.US, Android 4.0.4.

This sounds like the Verizon Rremote Access Server (RAS) is not authenticating you and is booting you off.

Dumb Question. Are you subscribed to the Hotspot Service?

You might have Verizon (at a store) try to re-provision the service by turning your phone off there, then have them take you off and putting you back on. Then turn the phone on and see if it works.

This gimped hot spot software Verizon commissioned for their monetizing purposes is a real pain. They should just use OEM android tethering .apk and just open it up and leave it alone for their customers to use or not as they see fit. But that's just my opinion. Doesn't do much to fix your issue.
